Abstract: Running sole structuring for a ski, especially for a cross-country ski. The object of the invention is to provide a new profiling which combines optimum gliding and climbing characteristics. Therefore, it is the object of the invention, to provide a suitable shaping of the profiling which fully considers the special requirements under different snow conditions as well as the special loadings of the ski during the push-off and gliding phases, as well as the process of sticking and gliding friction and the transitional phases associated therewith directly. This object is solved according to the invention by the provision of exclusively straight, vertical and parallel arranged profile edges with respect to the direction of the run which are also two-dimensional in the plane of contact with the snow and are statistically arranged and, wherein the adjacent pairs of climbing edge rows lying behind each other lie on a gliding arc. It is preferred when the mean edge length ( &upbar& bn) in the push-off region (A) is the smallest and increases continuously and/or discontinuously toward one ski tip, respectively ski end, and wherein in the end region of the longitudinal extent of the profiling the maximum value for the mean edge length ( &upbar& bn) is attained.

Abstract: The invention relates to a process for treating cast iron melts with silicon carbide. In this process, the silicon carbide used is subjected, before being introduced into the cast iron melt, to an oxidizing treatment in such a manner that the individual SiC granules are coated with a covering containing silica. A silicon carbide of this quality can be manufactured, for example, by subjecting the SiC in granular form, in a static or agitated mass, to an oxidizing atmosphere, such as air, oxygen or water vapor, at temperatures within the range of 900 DEG -1600 DEG  C. and subsequently subjecting the agglomerates formed to gentle comminution to expose the SiC surfaces which, as a result of the formation of an agglomerate, completely or partially escaped the oxidizing attack.

Abstract: The purification process is carried out in two stages. In the first stage, pulverulent active carbon in finely-divided form is added to the waste water. The solids materials are then separated by conventional mechanical separating processes. The liquid phase prepurified in this manner is then allowed to trickle in a second stage through an active carbon adsorption tower, air being forced at the same time through the adsorption tower. The process has proved particularly valuable in the purification of pesticide-containing waste water.

Abstract: For the non-deforming treatment of moving sheet material, e.g. for squeezing out the rolling emulsion in cold strip rolling mills, opposing, axially adjustable rollers 1, 2 are used as squeeze rollers which are slightly S shaped or bottle-like over the entire surface length so that the contours of two rollers located on both sides of the roller gap complement one another only when these rollers are in a specific relative axial position. In other axial positions the roller gap becomes narrower either in the middle or at the ends of the roll surface so that, through axial adjustment of the rollers irrespective of the deflection of the rollers and/or deviations in the plane- parallelity of the surfaces of the strip B, an even squeezing effect or other even non-deforming treatment of the product can be achieved over the entire strip width. Moisture sensors 51 - 54 can also be provided between successive contoured pairs of rollers 1, 2 and 1', 2', the axial displacement of the second pair of rollers 1', 2' being controlled according to the signals from these in order to remove any remaining area of moisture 50.

Abstract: A method and system are provided for detecting and monitoring the treatment of eye disease by determining the presence of visual field defects. The method utilizes eyeglasses having a pair of cross-polarizing lenses selectively adjustable for varying the amount of luminance of an Amsler grid as observed by the patient through the eyeglasses. By adjusting the relative polarization of the lenses separately for each eye until the patient is barely able to see the Amsler grid, the sensitivity of the patient's eyes to the presence of scotomas is greatly increased. By having patients record the presence of scotomas while observing the Amsler grid through the eyeglasses, it is possible to screen patients for visual loss associated with various eye diseases, such as atrophic SMD. Recording the existence of scotomas on a periodic basis enables an ophthalmologist to determine whether atrophic SMD may be advancing to hemorrhagic SMD requiring treatment to prevent permanent loss of central vision.
